HOISTING AND CONVEYING APPARATUS.

. SPECIFICATION forming part of Letters Patent No. 755,681, dated March29, 1904.

Application filed November 17,1902. SerialNo. 131,634. (in; model.)

To all whom it may concern:

Be it known that I, TIMOTHY LONG, a citizen of the United States ofAmerica, and a resident of Cleveland, in the county of Guyahoga andState of Ohio, have invented certain new and useful Improvements inHoisting and Conveying Apparatus, of which the following is aspecification.

' This invention relates to means for unloading and conveying ore orother material from the holds of vessels and depositing it into cars orother receptacles in a convenient and expeditious manner; and itconsists of a trestleframework supporting a traversing carriage uponwhich is provided a vertical hoisting device and a conveyer forreceiving and depositing it in required receptacles.

The invention consists in the peculiar construction and combination ofmechanisms adapted for carrying out the purposes stated, substantiallyas hereinafter described, and pointed out in the claims.

In the accompanying drawings, Sheet 1, Figure 1, is a side elevation,partly in section, of my new hoisting and conveying apparatus. Sheet 2,Fig. 2, is a front elevation of the apparatus. Sheet 8, Fig. 3, is a topor plan View of the apparatus with the upper framework removed. Sheet4:, Fig. L, is a vertical sectional view of the hoisting and conveyingpart of the apparatus. 7

In Figs. 1 and 2, A represents a dock or wharf, by the side of which avesselor boat is to be moored, from which the load is to be discharged.

B is a trestle-framework situated near the edge of the dock and ofsuflicient height for railway-cars to pass under. On the top of thetrestle are provided track-rails b 6, upon which the carriage whichsupports the elevating and conveying mechanisms can be traversed.Beneath the said track and sufliciently high above the dock for cars topass under are provided large troughs or slanting-bottom bins O O forreceiving the contents of the conveyer. On, one side of the troughs areprovided dischargeopenings D D, having sliding doors D D, which areoperated by means'of hand-levers d d, fulcrumed to the posts of thetrestle A and connected by links 03 with the said doors D.

E is a carriage-frame supported on the track-rails b b. F is an oblongcarriage-frame supported and traversable on-said carriage E transverselytherewith.

e are rollers set in the side rails of carriage-frame E, upon whichcarriage'F rests and rides.

f f are rollers attached to the corners of carriage E and which roll onthe lower flange of carriage F, designed for holding said carriage Fdown and prevent its tilting over by the weight on its opposite endwhenever said carriage may be run out forward.

G is a rotatable hopper supported on the forward end of the carriage F,intended to receive the ore elevated and discharged from verticalelevator.

G is a turn-table attached tothe under side of the forwardend of thecarriage F, sitting in a circular bed G".

g is an annular row of rack-teeth on the periphery of the turn-table G.

9 represents ball-bearings in the bed G, upon which the turn-tablerides. The hopper Gr also rides on ball-bearings g" and also has annularrack-teeth g H is an elevating-conveyer consisting of a beam made offour plates h it h h, forming a hollow beam, in which a bucketed chainbelt I is made to travel. The beam H passes through v a square hole inthe turn-table, by means of which it is made to rotate on its verticalaxis when required.

At each end of the carriage F are placed posts J J, the two at each endmeeting at the top and are joined by an overhead rail M. The elevator His suspended by a cable N, passing over pulleys O O at the top cornersof the frame J J M.

K is a pulley-frame attached to the top of beam H by a swivel-joint In,by means of which the elevator may have rotative motion on its axiswithout twisting the cable.

This keeps the elevator-beam Hsteady in its upright position. On theopposite endof the cable is attached a counterbalance-weight W, for thepurpose of equalizing the weight upon the carriage F.

To the lower end of beam H is provided an arm H, in which theconveyer-buckets play, and is for the purpose of having the conveyer,reach out around to the sides of the vessel,

thus giving it a wide scope for take-up.

Q is a connecting-conveyer supported on the carriage F, consisting of abeam similar to beam H, and is provided with a traveling drag-belt L. Itis designed for hauling the ore received from the hopper along over thetroughs and dropping into them. The conveyer-beam Q has openings Q,.provided with sliding doors q, adapted tobe opened at such points asmay be required for discharging the ore and letting it fall into thetroughs, from whence it may be dropped into the cars below.

The motive power used for operating this apparatus is electricity. Theseveral movements are operated independently by separate motors in thefollowing manner: On the top of elevator-beam H is placed motor "No. 1for operating the hoisting-buckets. On the end of conveyer Q, is placedmotor No. 2 for operating the drag L. It is also connected by bevel-gearand a shaft R with the hopper G by a bevel-gear 1*, whereby both thedrag and the hopper are operated simultaneously. The hopper is dividedinto compartments, in the bottoms of which are openings H, whichregister with the inner end of the conveyer Q, so that as the hopperrotates it will discharge its contents from the compartments insuccession as they come over said conveyer. On the carriage F is placedmotor No. 3, connected with the turn-table G for operating the turningof the vertical elevator to have its arm H rotate in the hold of avessel to reach a wide sweep. On the carriage F is also placed a motorNo. 1, having drums Y Z, having ropes y 2, connecting them with thecarriages E and F, used for shifting them in position relatively on thetrestle. The drum Z is for moving the carriage F outward to bring theelevator H out over the hatchways of vessels. The drum Y is for movingthe carriage E along on the trestle A to shift the elevator to otherhatchways. On the top corner of the framework J J M is also placed asmall motor No. 5, connected with cable N. This is employed for raisingand lowering the elevator H. Wires from a suitableelectric-current-supply source are to be connected with these motors andwith a switchboard located in some convenient place on the trestle. One

operator would be enabled to manipulate the entire apparatus with easeand despatch.

Having now described my invention, whatI claim is 1. In a hoisting andconveying apparatus, a vertical elevator, consisting of a hollow beam, aswiveled pulley on the top of said beam, and a pivoted extension on itslower end, a cable supporting said beam by suspension, said cablerunning over pulleys on the elevator-carriage frame, and having acounterbalance-weight; a bucketed elevator supported and operated insaid beam, and a motor mounted on the beam for operating the elevatorsubstantially as described.
